. SPRAYING-NOZZLE.

Specification of Letters Patent. Paijntd July 23, 1918 l Applicationfiled March 27, 1917. Serial No. 157,762.

To all whom it may concern:

Be it knowny that I, OSCAR SMIEDEL, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois,haveinvented lcertain new and usefnlV Improvements in Spraying-Nozzles, of`whichthefollowing is a specification.

The present invention has to do with'certain improvementsf in sprayingnozzles Afor usein connection with garden hose and the like, although itwill presently appear that ,the features of `the, present inventionV arein "no" wise limited to thisparticular `class of service.v H M The mainobjects of the present invention are to provide a very simple form ofconstructionlof spray nozzle, but a form which nevertheless will be veryflexible and can be very easily handled by the user. Also to soconstruct the nozzle that the spray maybe very flexibly controlled bothas to volume and character.

Other objects and uses of the invention willappear from a detaileddescription of 25 the same whichl consists in the features ofconstruction and combmations of parts here- ,inafter described and`claimed. Referringto the drawings: i

Figure 1 shows a front or end view of the 3.0 spray nozzle with thevalve plug turned into such aposition aste partially open one of t, .theorifices; Fig. 2 shows `a vertical section taken on the line 2-2 of Fig.1, locking in the direction of the arrows; i t v Fig. 3 shows ahorizontal section taken on a fthe line 3-3 of Fig. 2, `looking in thedirection of the arrows;

Fig. 4 shows a si Plug; and r Fig. 5 shows an end View corresponding vtoFig. ,4,

i Referring to the construction shown in the several figures, the nozzleis conveniently provided vwith an lelongated portion which serves as ahandle by means of which 'the nozzle is conveniently l grasped andmanipulated by the operator.' The rear end of this portion is threadedat 7 for attachment to the terminal of the gardenhose in the usualmanner. Near its front end `the elongated .portion G is enlarged as at 8for the accommodation of the plug valve which is shown de elevationofthe valve in detail in the various figures and separately in Figs. `4:and 5.v This enlarged portion 8 is 4provided with `a circular taperedsocket within which the plug valve 9 seats.'y

The front end 10 of thenozzle is preferably flared or spread out in themannershowny 1n the several figures so as to permit a free discharge ofthe spray, ywhileat the same` time giving the nozzle a finished andcompleted appearance. A discharge orifice 11 best shown in Figs. 1 and 3occupies a central position within the flared portionlO.

The plug valve itself is conveniently made of circular tapered form. Ithas the central stem 12 which passes through the rear wall 13 of themember 6. The stem 12 is somewhat contracted in its portion 14 where itpasses through the wall 13, and said portion 14C is also tapered so astov make a water-tight fit at the same time that the body portion of theplug valve is seated in water-tight man*- A nut 15 and washer 16 areplaced on the contracted portion 14: of the stein 12 in the manner whichwill be readily understood from the figures.

Ingits central portion, the plug valve is provided with a pair ofcircular partitions v 17 and 18 which provide a narrow slot 19` betweenthem. Around the periphery of the wall of the plug are the openings 20,21, 22, and 23 of graduated sizes. The opening 20 is shown as beingcircular, whereas the openings 21, 22, and 23`aie` each in the form ofan elongated slot. Examination of Fig. 4 reveals the fact that theseslots are of graduated widths. The opening 11 inthe front end yof themember G is of suflicient width to accommodate the entire stream .de'

livered by the widest one of the openings in the plug valve9. Thepartitions 17 and 18 4are warped or tapered or varied in Acontour jinsuch-a manner that adJacent to each of the openings 2]., 22, and 23, thewidth of the space 19 is just equal to the width ofthe said opening, thepartitions 17 and 18 `tapering at points between theopenings, as shownin Fig. 4. Consequently, thewater deliveredr through any one of theopenings 21, 22, or 23 is compressed or drawn into a sheet of the samewidth as the opening through which it is to be delivered. u

The partition 17 adjacent to the open side of the plug valve is providedwith an inner there being a discharge orifice in said partmemberproviding therebetween an annular tion, of a circular valve memberWorking in passagewav in communication with the slotthe socket member ata point adjacent to ted opening, and there being an opening for 10 saidpartition, there being a slotted periphthe admission of Water to saidpassageway,

5 eral opening in said valve member adapted substantially as described.
